Abstract
An implantable atrial cardiovertor applies cardioverting electrical energy to atria of a heart with reduced discomfort to a patient. The cardiovertor includes a storage capacitor having a capacitance and a discharge control for controlling discharge of the storage capacitor to apply the cardioverting electrical energy to the atria of the heart. The discharge control causes the applied cardioverting electrical energy to have a biphasic waveform having a first phase and a second phase of opposite polarity and equal time duration. The time durations of the first and second phases are each greater than four milliseconds, and the capacitance of the storage capacitor is greater than or equal to 120 .mu.F.
